LAMP AND HEATER.

Application filed October 25, 1923. Serial 110.670,710.

' specification.

rIhis invention relates togan improvement in -electrical apparatus, and the same has for its object to provide an apparatus which may 'be' used vfor illuminatingpurposes or vfor heating or cooking. The apparatus may" also be usedl simultaneously both. for illuminating and heating or cooking.

'My invention consists of a novel construction of a combi-ned electric heater and elec- 'tric table lamp, wherein I utilize the hollow base of the lamp structure as an electric heater, so that when the lamp is inverted the heater can be operated to heat the room or if desired to heat an article as water, etc. A further object of this invention is to construct a table `lamp with a hollow base,. the latter being utiliedas a heating compartment and adapted to' operate simultaneously with the lamp. e

A furtherobject of' this invention .is to constructv a. combined electric table lamp andelectric heater, the latter; disposed within the base of the lamp. A lamp'shadb normally resting on supports and adapted to be'utilized as a cover fo-r articles to be heated`v when-the lainp is inverted and the` heater is in use.

A further object of this invention is to provide a combined lamp and heater with abutments for a shade and when the lamp isV in an inverted position'the abutments act as supports for the lamp and heater.

A further object of this invention isl to' construct a combined electric lamp and electric heat reflector. Y

In the drawings; Figure 1 is a front view partly in section, made in accordance, with my invention. Y

Figure 2, is abottom view of my device.

Figure 3, is afront view of the device in an inverted position.

Figurey 4, is a front view partly in section of the device used as a heat reflector.

Figure 5, is awdiagrammatic view of the wiring. u

Referring to the drawing, the numeral l, denotes a standard for a -lamp having its lower portion formed into a hollow base 2.

To the upper part of the standard there is A shrunlior otherwise permanently attached ra sleeve 3, to which there are integrally `fixed laloutments or supports 4, these abutments are made of liexible metal and the ends 5, are turned upon themselves so as 'to form smooth resting means. Upon the abutments a shade 6, is placed, the abutments preferably being flexed so as to hold the' shadein a snug manner. At the upper end of the standard an electric bulb 7 is screwed or otherwise attached.

IVithinthe-hollow base 2, I place my heater 10, which is a bare wire supported and properly insulated by the asbestos or other non-conducting material 11, the latter is in turn fixed tb the base 2, by means of lugs 12, and. screws or bolts 13. To the bottom. of the base I have placed a heat insulating ring 14, and within this ring I vplace a grid 8,01' any meshed wire or any metal of highly heat resisting quality. The grid and asbestos ring are both attached to the bottom of the base by means of long screws 15. Underneath the base I place an asbestos ring 16, to prevent any heat reaching a table or other support.

Wires 17, 17, lead t ie current to a switch 18, which throws the current either to the lamp or heater or'if desired to both simultaneously. Figure 5, clearly shows the wiring arrangement. In entering through the wire 17, the switch 18, and the segment 22, the current enters and lights the bulb 7, and leaves by the wire 17 thus completing its circuit and only the bulb is affected. Should the switch be turned so that 'it covers the segment 23, then only 'the heater is affected, however, if the switch is so placed that it covers portions of segments 22, and 23,*tlien the current divides in parallel and both bulb andheater are affected.

In Figure I have shown the device in an inverted position and with current turned on the heater is in use. If desired the shade may be placed over the heated object, and thus make 'the heat more intense and thereby cause an oven effect.

In Fig. 4, I have illustrated a modification of my device which embodies a heat reflector. The reflector consists preferably of arhighly polished metal shell 31,v which is parabolic or dome-shaped and yserves to reflect the heat waves receivpd from the heater and direct them outwardly fro the inner concave surface. :The heater unit comprises, a suitable heating element such as a bare high resistance Wire 32, coiled helically upon a refractory cylinder 34C, of fire clay, asbestos or other suitable material. The Wiring around the refractory cylinder is done in any approved manner.

The vrefractory cylinder and reflector are fastened to a lug. 35, Within the standard 1. LThe Wide end ,86, of the reflector is held in position Within thebase by any desired means such as a flange 38, which is'fastened to'the base 2.

A grid 37, has the dual function of acting both as a support `for articles to' be heated and as aguard invariably used in lieatreflectors. This gridis also placed and held in positiori'by the flange '38. v

In order that' the column or shaft of reliected heat Waves may-be directed at varying angles as desired, I may provide a sivivel connection between the parabolic reflector and the support or stand.

Thus by the above described construction are accomplished amongpothers, the objects hereinbelore referred to. l

ils manyv changes could be made inthe above construction and many apparently Widely different. embodiments of this invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown inthe Vaccoinpanying dra-Wing shall be interpreted as illustrative and not in a limiting sense.

It is kalso to be understood that the language used in thefollovving claims is intended to cover all of the generic and specific features of the invention herein described.

to secure by Letters supporting the shade when the lamp is in an upright position, said means also adapted to support lthe lamp and heater in an inverted .position and so "arranged that both lamp and heater could be used simultaneously. e l
